Title: Substrate printing method
Inventor: IKEDA TOMOKO
IPC: H05K3/00
Filed: 1991-12-17
Abstract: PURPOSE:To distinguish between the inside and the outside of a substrate as well as to judge the mounted position of an electric circuit part from the back side by a method wherein a part layout chart is directly printed on both front and back sides of the substrate. CONSTITUTION:The name of a mounted part is printed in letters of normal form in the part layout chart 11 printed on the surface of a printed substrate, but the letters of the part layout chart on the back side of the substrate are printed inversely. The part layout on the back side of the substrate is printed in such a manner that the printed letters can be read from the back side. For example, when a part is mounted on the address 11-1 having the vertical shaft's address symbol G12 and the horizontal shaft's address symbol G, the part layout chart 11 printed on the substrate surface becomes hardly seen because it is hidden by the part, but the mounting of part can be conducted by looking at the part layout on the back side of the substrate. Also, as the name of mounting part of the part layout chart on the back side of the substrate is printed in inverted letters, the part can be mounted without making a mistake in distinguishing the front and the back sides of the substrate.
